The first one that I tried was a paid for version of standard.
It worked well.
I then tried the powepack version and that was better. I did that twice.
The main reasons that I now use gentoo are to get away from the 6 monthly upgrading, and gentoo's excellent portage system.
Given the reasonable cost of a powerpack (the powerpack + version is what they now call the Pro version and I didn't need that), it's worth the money.
